VENTILATING WINDOW STRUCTURE Ernest L. Anderson, Seattle, Wash. Application November 26, 1956, Serial No. 624,464?

11 (Ilaims (Cl. 2tl52.2)

The present invention relates generally to ventilating windows having both fixed and sliding panes, and more particularly to windows of this type having a unitary border frame which not only defines a vent opening and one or more light openings for fixed panes, but also serves as the track for a unitary sliding vent frame to selectively cover the vent opening.

My invention aims to provide an improved such window of simple and economical construction in which the sliding vent frame is thoroughly weather stripped.

A further aim is to provide such a window in which the primary border frame is extremely versatile in that it can be used not only for sliding vents, but for hinged vents, all fixed panes, or a combination thereof.

Still another object is to provide an improved such window which can be readily assembled and in which the sliding vent'frame can be easily removed for cleaning from the inside of the room.

With the foregoing objects and advantages in view, and which will appear and be understood in the course of the following description and claims, the invention consists in the novel construction and in the adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawings:

Fig. 20 is a fragmentary vertical sectional view showing the border frame being used with a hinged vent frame fabricated from the sliding vent frame material.

In order to avoid confusion in terminology I shall hereinafter use the words inside, outside, inwardly and outwardly as meaning that the object is closer or further from the center of the window in the general plane of the window,-. and not that the object is further toward the indoor or outdoor side of the window.

Continuing now to a description of the illustrated embodiment, the primary border frame is fabricated from lengths of a single extruded shape shown in Fig. 4 and designated All. Facing inwardly toward the center of the window, the frame presents inner and outer step flanges 21, 22. which are interconnected by a riser flange 23. At its indoor edge the inner step flange 21 has an inwardly directed riser flange 24 defining the light opening and an outwardly directed trim bead 25. The outdoor sides of the step flanges 21, 22 jog outwardly to form inwardly faced rabbets 26, 27. As is a common practice,

the frame Zl may be formed with a generally U-shaped decorative molding head 28 which has a short leg 28a joining the outer step 22 and a long leg 28b merging with an outwardly directed nailing flange 30.

in the example illustrated in Fig. 1 the primary frame bars Ztl define a rectangular light opening which is vertically bridged across its outer step and riser 22, 23 by a two-piece muntin bar whose backed halves are numbered 31. These halves each have step and riser flanges 22a, 23a and a rabbet 27a which correspond to flanges 22, 2.3 and outer rabbet 27, respectively, of the bars 20. Each half 31 also projects oppositely of the step flange 22a by a head 32 to provide a groove 33 facing indoors. Since the muntin bar does not bridge the inner step and riser 21, 24', the head and sill sections of the latter are uninterrupted throughout their full length thereby leavmg these sections of the inner riser free to serve as tracks for a sliding vent frame.

The vent frame is primarily fabricated from a bar 34 shown cross-sectionally in Fig. 6. At its inner s1de the vent frame has a riser flange 35 defining the vent light opening and a step flange 36 formed at its outdoor side with a rabbet 37. Extending outwardly as channel legs from the side edges of the step flange 36 are flanges 38, 40, the former of which has its free edge turned outdoors to provide a retainer or stop 41. Desirably this stop should be no wider than the jog forming the inner rabbet 26.

A channel weather strip 42a having bristles 43 rooted to its inner side faces is housed in the head section of the vent frame and is urged upwardly toward the stop 41 by leaf springs 44. These springs are anchored at one end of the step flange 36 and each has its free end longitudinally slit at a distance from the indoor edge corresponding to the width of the weather strip 42. The outdoor finger 45 of the resulting two fingers is bent upwardly somewhat to engage the outdoor face of the weather strip to cooperate with the indoor vent flange 38 for holding the Weather strip against lateral motion while at the same time permitting vertical movement of the weather strip with respect to the vent frame. As best shown in Fig. 15, the base of the weather strip 42 is fitted with nylon shoes 47 for riding against the head inner riser 24 of the primary frame.

Complementing the upper weather strip channel 42a is a similarly shoed weather strip 4212 which is stapled to the ridges of a corrugated spacer 48. This spacer seats against the base of the step flange 36 of the vents sill section and has sufficient resiliency to permit the weather strip 42b and the spacer as a unit to be pressed into place above the stop 41 of the sillsection. In this manner no auxiliary fastening means is required to hold r 3 the. spacer and weather strip unit in place. The meeting an'ib section of the viit frame is similarly equipped with a weather strip, denoted 42;. Weather stripping of the vent is completed by a brush strip '49 which is seated in one of the mutin bar grooves 33. It is also desirable to provide the head and outer jamb of the vent opening with flashing or valance strips 50 which are fitted into the inner rabbet 26 and overlap the vent frame slightly when such is in its closed position. The other jarnb section of the vent frame is fitted with an insert 51 formed with a beveled keeper groove 51a for guiding a slide bolt 52 having a handle 52a. This bolt selectively cooperates with keeper openings 53, 54 cut in the inner step 21 of the head of the primary frame. Opening 53 1s engaged by the bolt to lock the vent in a fully closed position whereas keeper opening 54 can be engaged by thejbolt to lock the vent in a partially open night latch position.

As best shown in Fig. 3, the fixed pane 55 for the primary frame is set outdoors of the sliding vent, and

namely between the outer step flange 22 of the primary frame and the-corresponding step flange 22a of the muntin bar. The fixed pane 55 and the vent pane 56 can be putty glazed in position or can be supplied with a rubber or vinyl glazing gasket 57 as shown. In the latter instance the panes are held in position against the respect ve riser flanges by glazing beads 58 of an unequal Z-shape which have outwardly directed retainer flanges 60. These flanges fit into the rabbets 27, 27a in the case of the fixed panes 55 and fit into the rabbets 47 of the vent for containing the vent pane 56.

To install the vent frame in the primary frame, it is first lifted to seat the upper weather strip 42a on the head section of the inner riser flange 24. Then, the vent frame is urged upwardly to depress the leaf springs 44- sufliclently to permit the extreme lower edge of the vent frame to clear the border frame. The upward pressure on the vent frame is then released to permit the lower weather strip 42b to seat itself on the inner riser flange 24.1 With the vent thus in place smooth and quiet sliding action is achieved by virtue of the fact that the nylon shoes '47 are the tracking surfaces of the vent. A handlej 61 is mounted on one of the jamb sections of the verit'frame for manually sliding the vent frame.

As shown in Fig. 16, instead of having separate handles 52a and 61 for the slide bolt 52 and vent frame, a single handle 153 can be utilized to slide the vent and throw the bolt. This hand1e 153 projects indoors of the vent frame and has a flat vertical foot 1530 which is secured to a modified bolt 152. The latter rides in a modified keeper 151 having a longitudinal rabbet 1511; directed oppositely from its keeper groove 151a. Facingf generally in the same direction as the latter is a beveled face 151a which is intended to wipe the stop 41 of the vent frame. The outer face of stop 41 is desirably rounded so that the keeper 151 can be forced into position with its rabbet 151b over the flange 40 of the vent frame and its beveled face 1510 wedged past the rounded stop 41. Along its indoor edge the keeper 151 has an L-flange 151d which projects indoors of the mouth of the groove 151a to lie flush with the indoor face of the vent flange 38. This L-flange is slotted at 151e to receive the foot 153a of the handle 153. The slot 151a is longer than the foot 153:: to permit limited travel of the bolt 152. At its upper end the latteris formed with a projecting finger 152a for selective reception by keeper openings 154, 155 in the bead of the primary frame.

In Fig. 19 I have illustrated a modified glazing gasket 157 in a relaxed state, that is to say, Without a pane. The gasket has external ribs 157a along-its sides and ribs 157b along its bottom. These ribs permit flexibility in the size of the pane received. Gripping of the pane is aided by an opposed pair of inner ribs 157a and by way of the fact that the mouth of the ga sket is narrowed.

Out-turned flanges 157d are provided to seat on the inner edge of the frame and the innf edge of the glazin bead 58.

One of the chief advantages of my improved ventilating window is the great versatility of the primary border frame in that it can be used for uniformity in the same building, not only for a sliding vent, but also for a hinged vent or for a window having nothing but fixed panes. In the latter instance the panes can be set against the inner riser flange 24 and the inner rabbet 26 used for the glazing head. If such a window is to have more than one light it can be subdivided by extending lengths of the muntin bar between the inner step and riser flanges 21, 24. Screens or storm sash can be set in place against the outer risers 23' while the inner risers are serving as tracks for sliding vents or to receive fixed panes. As shown in Fig. 5 by frame bar 2011, the frame can be modified to eliminate the molding 28. In this instance a nailing strip 3% can extend from the outer riser flange 22 and a slight outdoor trim bead 28c may be provided.

in Fig. 20 I have illustrated the use of a hinged vent 62 which is fabricated from Z-bars and has its pane 63 putty glazed for purposes of example. It will be noted that the hinges for the vent have one arm 64 riveted to the center section of the molding bead 28 of the primary border frame and a complementing longer arm 65 riveted to the bent frame. These hinge arms are connected by a pivot pin 66 so that the vent frame can swing from an open position to a closed position wherein the two outer and inner legs of the Z-bar vent frame contact the outer and inner riser flanges 23, 24.

It is thought that the invention will have been clearly understood from the foregoing detailed description of my now preferred illustrated embodiment. Changes within the spirit of my teachings may be resorted to without departing from the invention and it is accordingly my intention that the hereto annexed claims be given a scope in their construction fully commensurate with the broadest interpretation to which the employed language admits.
